To allwlwmlit may concern: 4

Be it known that I, SIMON E. Hormv, a citizen of the United States, residing at Dacoma, in the county of Woods and State of Oklahoma, have invented certain new and useful Improvements'in Two-Row Listers, of which the following is a specification, reference being had-to the accompanying drawings.

This invention relates to the art of farming implements, and particularly to an improved two-row lister, especially adapted for attachment to the rear of a tractor, and one of the objects of the invention is to provide means for connecting a beam structure adjustably to the frame of the lister,

whereby the beam structure may be adjusted relatively to the lister frame and-vice versa, in order to adjust the listers in different positions relatively to the soil.

' A further object of the invention is the provision of a beam structure comprising a hollow tubular connector rectangular in cross-section adjustably connected to the lister frame and pivotally mounted between a pair of braces, so-that the rear end of the connector may be adjusted relatively to the lister frame on its pivot, so that the forward end of the connector may accommodate itself and be connected .to tractor frames of different heights, and also whereby the listers may accommodate themselves to the irregularities of the ground or soil.

.While the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the in vention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention. comprises further features and comblnatlon of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a plan view of the improved two-row lister constructed in accordance with the invention, showing the connection between the connector and the lister frame,

and also showing the braces.

Fig. 2 is a sectional view on line 2 -2 of Fig. 1. a

Serial No. 304,374.

vation and also showing'the connector adings, 1 designates a conventional form of lister frame, ,to which the beams of the listers are connected, as shown at 2.- Said lister beams are provided with the usual and conventional form of listers 3. Secured as at 1 to the forward rail of the lister frame is a plate 5, provided with forwardly extending spaced arms 6. A hollowtubular connector 7 is provided, and in one end of which a projecting arm 8 of a clevis member 9 is'secured by means of the bolts 10. The spaced arms 6 engage 'on opposite sides of the clevis 9, there being a bolt 11 passing through the spaced arms 6 and throughany one of the apertures 12 of the clevis 9, so that by removing the bolt 11, and adjusting the same in any of the apertures 12 of the clevis, the rear end of the connector may be adjusted relatively to the lister frame and vice versa. A pair of diverging brace irons 13 is provided. Forward angularly bent ears 14 of the brace irons are secured to the connector by means of the transverse bolt 15, which is provided with the usual nut, so that the connector may move pivotally on the bolt. The clevis 9 is arcuately curved, concentric with the bolt 15, so as to permit the connector to be adjusted, and by adjusting the connector, it 7 will be seen that the lister frame is capable of moving pivotallv relatively to the conof the lister frame, as shown at 17, whereby the lister frame is capable of movement. Secured in the forward end of the connector as shown at 18 is a connecting strip or plate 19 having an opening or aperture 20, for the, reception of a pin (not shown) of a clevis (not shown), whereby the two-row lister may be connected to a tractor (not shown), so that the lister maybe drawn over the ground or soil.

The invention having been set forth, what is claimed as new and useful is:'

1. The combination with a lister frame provided with a pair of listers, of a hollow tubular connector to be pivoted to a tractor,

and in turn having its rear end provided with a clevis connection with the lister frame, a pair of braces, a single transverse bolt connecting theforwardjends of the braces to the connector, said braces diverg ing rearwardly and having their rear ends secured to the ends of the lister frame.

2. The combination with a lister frame providedwitha pair of listers, ofa hollow tubular connector to be pivoted to a tractor, and in turn having its rear end provided with a clevis connection with the lister frame, a pair of braces,a single transverse bolt connecting the forward ends of the braces to the connector, said braces divergi'ng rearwardly and having their rear ends secured to the ends of the lister frame, said clevis connection comprising an arcuate clevis concentric with the single securing bolt of the braces and provided'with a'plurality of; apertures, said clevis having an entension extending into the rear end (if-the connector, meansto secure the extension in the connector, and a plate secured to the lister'frame and provided with spaced arms extending forwardly, and means passing through the arms and through any one'of the apertures for adjustably connecting the clevis between the arms.

In testimony whereof I hereunto affix my signature in the-presence of two witnesses;
